Legal claims defining the scope of protection. Each claim is shown in both the original legal language and a plain English translation.
1. A transmitting apparatus comprising: a processor configured to arrange, in a physical layer frame including a preamble and a data portion, transmission information immediately after the preamble and at a head of the data portion as an area that is extractable temporally before other information arranged in the data portion; and a transmitter configured to transmit the physical layer frame as a digital broadcast signal, wherein the transmission information includes pieces of information among at least two of time information for synchronizing a transmitting side and a receiving side, header compression information for compressing header information of a packet, and channel selection information for selecting a service, and the pieces of information are ordered in the data portion as follows, the time information, then the header compression information, and then the channel selection information.
A transmitting apparatus efficiently sends periodically updated information. It uses a processor to organize specific "transmission information" within a digital broadcast signal's physical layer frame. This frame includes a preamble and a data portion. The processor places the transmission information immediately after the preamble and at the very beginning of the data portion. This arrangement ensures the information can be extracted and processed earlier than other data in the frame. A transmitter then sends this frame. The transmission information itself includes at least two of the following, in this precise order: time synchronization data, header compression details for packets, and channel selection data for services.
2. The transmitting apparatus according to claim 1 , wherein, in the physical layer frame, the data portion includes one or a plurality of PLPs (Physical Layer Pipes), and the transmission information corresponding to each PLP is arranged at a head of each PLP.
A transmitting apparatus, as described in CLAIM 1, organizes specific "transmission information" within a digital broadcast signal's physical layer frame for efficient, early extraction. The frame's data portion contains one or more Physical Layer Pipes (PLPs).
